Final answer:
EMT-Bs can administer an over-the-counter nasal spray and use other techniques to control an uncontrolled nose bleed.
Step-by-step explanation:
An EMT-B can administer an over-the-counter nasal spray such as oxymetazoline to control an uncontrolled nose bleed. The recommended dose is two sprays in each nostril. The medication is administered intranasally.
In addition to the nasal spray, an EMT-B can also use sterile gauze or cotton to apply direct pressure to the bleeding area, tilt the head forward to prevent blood from pooling in the throat, and apply cold packs to the nose and cheeks to constrict blood vessels.
